Development of a Harvester for Cable Logging

在日本，70%的森林面积的坡度超过15。因此，电缆测井系统被频繁使用。目前已采用的电缆测井系统约有120种，其中30种适用于选择性切割、部分切割、清切和间伐作业。在这些作业中，节流工在伐木现场走动时，必须携带一个连接在主线末端的节流钩。特别是，在陡峭的山区，颈长面临着危险而艰苦的劳动，为了将颈长从这一危险而艰苦的劳动中解放出来，作者开发了一种电缆采伐收割机。该收割机由无线遥控小车和采树头组成。这些机器进行了匹配，然后在操作和实际应用中进行了测试。因此，未来必须对其采伐操作的几个方面进行改进。显然，新机器投入实际使用之前需要一段时间，但这台机器似乎显示出未来实际使用的很大希望。

In Japan, seventy per cent of the forest area has a slope of more than 15 in gradient. Consequently, cable logging systems are frequently used. There are about 120 different cable logging systems that have been adopted and 30 of them are suitable for selective cutting, partial cutting, clear cutting, and thinning operations. For these operations, the chokerman has to carry a choker hook that is attached to the end of a main line as he moves about the logging site. In Particular, the chokerman is faced with dangerous and hard labor in steep mountainous areas.The authors developed a harvester for cable logging to release the chokerman from this dangerous and hard labor. This harvester is composed of a radio control carriage and a tree harvesting head. These machines were matched and then tested both in operational and practical applications. As a result, future improvements must be made regarding several points of its felling operation.It was clear that some time is necessary until the new machine is put into practical use, but the machine appears to show much promise for future practical use.
